Ceramic on ceramic - Be careful.

SWMBO had a slight mishap last night.
She made some mini pizzas (prefab crust, they suck but I don't complain).
She was cutting them.
Using the ceramic knife that I got her a couple of years ago, cutting them on a CorningWare plate.

The plate broke! I won't say it shattered, but it broke into about 6 pieces.

Sounds like the knife cut the plate. And like peanut brittle, it doesn't cut, it fractures.

Exactly. That was my thought when it happened. She applied just enough pressure to break the glaze on the plate, which is perfectly logical, but something that is easy to overlook when you've been cutting steak on ceramic plates for 50 years without incident.

But this does tell me that I will not be buying a ceramic steak knife set unless we switch to wooden plates.

Better the plate breaking than the knife. Much cheaper to replace corningware plates than a good kitchen knife.

The plate might have been weakened by a previous drop. I love these glass dishes but when they go . . . they tend to make quite a show.

Not this one.
I think I spent $15 on the knife at CVS. The plate was a set that she special ordered 10 years ago to match the pattern on something else she had.

My guess is that it would have gone the next time it was in the dishwasher or dropped. Must have had some cracks or deep scratches. I doubt an inexpensive ceramic knife would harm Corning-ware. I remember being at my grandmothers house and hearing a POP in the cabnet that no one was near. People from 2 rooms over came running in it was so loud, and we opened the cabnet to find a big Corning-ware platter had shattered into thousands of square pieces.

Wow.

I've had a couple chip after being dropped, but never shatter, and never spontaneously.
Plate wasn't even that old (I don't consider 10 years to be old, I still have some Corning that my parents gave me 30 years ago, and it was at least 10 years old then!), and we got the set after the daughter moved out (we couldn't have anything glass in the kitchen with her around!). Pretty sure it's never been dropped... which brings us to thermal shock, which doesn't seem right for Corning.
